s ciaims. (c1. 10s-7) This invention relates to shingles and more particularly those made from composition roofing which, in practice, is generally slate coated.

The present shingle may be made in various forms, but is generally characterized by the fact that portions of the shingle are folded under at or adjacent the weather edge of the shingle, so as to reinforcethe weather edge and stiften the same and also to give increased thickness.

With the foregoing objects in mind and others, the invention embodies numerous other features which will be hereinafter more fully pointed out in the following detailed description shown in the accompanying drawing and set forth in the appended claims.

Th accompanying drawing illustrates different practical embodiments of the invention, but theing the blank of Figure 4. I

Figure 6 is a section on the line 6 6 of Figure 5.

In making a shingle such as shown in Figure 2, I start with a blank of the kind illustrated in Figure 1 and use for this blank composition roofinggmaterialt'which mayor may not be slate covered, either in whole or in part, as desired. I make the blank of such length that it may constitute a shingle strip or an individual as may be desired, but I have shown a four-in-one shingle strip and consequently the length of the blank is appropriate to this use. The blank is made somewhat wider however than the conventional shingle strip, so that the distance :z: between. line I and the upper edge of the blank is equal to the Width of the desired finished strip, so that the portion. 2 constitutes the body of the strip, while the portion 3 constitutes an integral extension beyond the body. At suitably spaced apart distances in the body, I provide the usual cut outs 4 which preferably extend down to the line I. From the line I, I form slots or cuts 5 in such manner that they have closed ends, i. e., they do not extend to the cut outs 4l or to the opposite ends of the strip, but leave aportion of the material undercut between these edges.

After` the formation of the .slots or cuts 5, the extension 3 is folded back under the body 2, to

give the finished shingle of Figure 2 from which it will be noted that the extension 3 underlies the cut outs 4 and extends above the upper ends of the same, so as to completely underlie the cut outs. 5

In practice I preferably make the extension 3, Which is folded under as stated, substantially equal to the overlap desired when the shingles are laid, so that there is in effect three thicknesses of the roofing material throughout the roof except at the slots or cut outs 4 where there is a minimum of two thicknesses at all points. There is thus obtained a very satisfactory roof covering and one which is well able'to withstandprolonged subjection to rain without any possibility o f leakage. Particular attention is called to the fact that in any event, the turned under portion 3 underlies the cut outs.

Strips of the character described may be nailed to a roof in the usual way; o r, if desired, the shingle may be unfolded slightly to permit the extension 3 to be nailed in place and then the shingle folded down flat again so that the heads ofthe nails underlie the body 2 of the shingle, in which case the nails may be placed very close to the weather edge of the shingle and will nevertheless be obscured from View.

The desired conformation of the weather edge may be accomplished by appropriately shaping' the slits or cut outs 5, such as shown in Figure 1, and then bending the shingle along the line I. The result will be that I will obtain a somewhat semi-hexagonal contour at the weather edge of the shingle, as shown in Figure 2. In Figure 2, all of the tabs at the weather edge are of the same shape, although they may be made of different shapes, as shown in the blank of Figure 3, where some of the slits or slots 5a are curvilinear, while others 5b are semi-hexagonal.

In Figure 4, I have shown a blank wherein the slits or cuts 5c are substantially U-shaped, s0 that when the blank is bent .along the line Ic, as shown in Fig. 5, the lower edge of the shingle strip will have a castellated appearance. If desired, the shingle of Figure 5 may further be 4.54

bent along the line Id, so that the free end of each shingle tab will -be bent under as indicated at 'I in Figure 6, so as to give increased thickness at the end of each tab. This concept may bev carried out with shingle tabs of different shape than that shown in Figure 5, such, for example,- as the semihexagonal type hereinbefore referred to.

In Figures 1-6 of the drawing, a four-in-one strip shingle is illustrated in each instance, but,

if desired, the invention may be carried out in a three-in-one or a two-in-one shingle or an individual shingle. In all of the foregoing gures, moreover, the turned under portion or extension Vis shown as equal substantially to the width of the overlap which the shingle is to have with an underlying shingle, but this may be greater or less. The shingle of this invention is a high cla shingle. It is not intended to be a shingle highly economical in thel employment of material, but is rather directed to a structure capable of producing a durable and water-proof roof and one which will be free from in many objections which havey been found in the use of ordinarystrip shingles.

` composition roofing material, but it may be made 'in asbestos or any other material.

Having thus fu11y described the invention, whatA I claim as new and desire to securejby Letters Patent is:

1. A shingle formed from a blank ot'rnaterial,

a. portion of the width of which is permanently bent under to form overlying and underlying portions integrally united at the line 'of the bend with the underlying portion of less width, than the overlying portionthe overlying portion hav` ing laterally spaced apart integral tab-like projections extending beyond the line of the bend and constituting part of the overlying portion and formed from the material of the underlying portion, the overlying portion being provided with cut outs extending into the body of the overlying portion from the line of the bend and for a distance less than the widthof the underlying portion and. interspaced with respect to. said laterally spaced apart tab-like projections. 2. A shingle formed from a blank of material, a 5 portion of the width ofwhich is permanently bent under to form overlying and underlying portions integrally united at the bend, the overlying portion having laterally spaced apart'integral tab-like projections extending beyond the 10 line of the' bend and constituting a part of the overlying portion and'formed from the material of the underlying portion, and said overlying portion having cut outs extending from the line of the'bend into the body of the overlying portion 15 and interspaced with respect to said laterally `spaced apart tab-like projections and being of less length than the width of the underlying portion. Y

3. A shingle formed from ablank of material, 20 a portion of the width of which is permanently bent under to form overlying and underlying portions integrally united at the bend,v the overlying portion having laterally spaced apart integral tab-like projections extending beyond the line of the bendv and constituting a part of the overlying portion and formed from the'material 0f the underlying'portion, the free ends of said tab-like projections being folded under vto impart increased thickness at the weather ends thereof, and said overlying portion having cut outs extending from the line of the bend into, the body of the overlying portion and interspaced 'with respect to said laterally spaced apart tablike projections and being of less length than the width of the underlying portion.
